Non-Hermitian phase-biased Josephson junctions
Jorge Cayao, Masatoshi Sato
We study non-Hermitian Josephson junctions formed by superconductors with a finite phase difference under non-Hermiticity, which naturally appears due to coupling to normal reservo…
Universal platform of point-gap topological phases from topological materials
Daichi Nakamura, Kazuya Inaka, Nobuyuki Okuma +1
Whereas point-gap topological phases are responsible for exceptional phenomena intrinsic to non-Hermitian systems, their realization in quantum materials is still elusive. Here we…
Generalized Thouless Pumps in 1+1-dimensional Interacting Fermionic Systems
Shuhei Ohyama, Ken Shiozaki, Masatoshi Sato
The Thouless pump is a phenomenon in which charges are pumped from an edge of a fermionic system to another edge. The Thouless pump has been generalized in various…
Extrinsic topology of Floquet anomalous boundary states in quantum walks
Takumi Bessho, Ken Mochizuki, Hideaki Obuse +1
Bulk-boundary correspondence is a fundamental principle for topological phases where bulk topology determines gapless boundary states. On the other hand, it has been known that cor…
Spin susceptibility for orbital-singlet Cooper pair in the three-dimensional SrRuO superconductor
Yuri Fukaya, Tatsuki Hashimoto, Masatoshi Sato +2
We study the spin susceptibility of the orbital-singlet pairings, including the spin-triplet/orbital-singlet/-wave representation proposed by Suh \textit{et al}., [H.\ G.\…
Non-Hermitian Higher-Order Weyl Semimetals
Sayed Ali Akbar Ghorashi, Tianhe Li, Masatoshi Sato
We study non-Hermitian higher-order Weyl semimetals (NHHOWSMs) possessing real spectra and having inversion (-NHHOWSM) or time-reversal symmetry $\mathca…
